The Amazon Echo is an attractively designed speaker and its voice-control system, anchored by soothing and smooth-sounding "Alexa," works well within its current limited scope. The speaker's Wi-Fi setup is relatively straightforward and you can also directly connect to the speaker via Bluetooth. The speaker plays loud and Alexa's voice sounds clear.

Harman Kardon's Esquire Mini is one of those products you'd love to receive as a gift, but you might hesitate to acquire on your own for $150 (£124.95 UK, $229 AU). It's part Bluetooth speaker, part high-quality portable speakerphone and part external battery charger. It's also one slick-looking product, with a slim unibody design (238 grams or 8.1 ounces) and retractable kickstand.
